| up- and down-regulation of fragaria x ananassa o-methyltransferase: impacts on furanone and phenylpropanoid metabolism. | a complex mixture of hundreds of substances determines strawberry (fragaria x ananassa) aroma, but only approximately 15 volatiles are considered as key flavour compounds. of these, 4-hydroxy-2,5-dimethyl-3(2h)-furanone (hdmf) is regarded as the most important, but it is methylated further by faomt (fragaria x ananassa o-methyltransferase) to 2,5-dimethyl-4-methoxy-3(2h)-furanone (dmmf) during the ripening process. it is shown here that transformation of strawberry with the faomt sequence in sen ... | 2006 | 16798852 |
| [identification and characterization of a flavonoid-3-o-glucosyltransferase gene from saussurea involucrata]. | the flavonoid-3-o-glucosyltransferas (3gt) is one of the most important enzymes for biosynthesis of plant secondary metabolites. in this paper, the homology analysis and gene special primers design were used. with the methods of modern molecular biology, the full-length gene of 3gt (genbank accession no. jn092127) which was cloned from saussurea involucrata kar. et kir by rt-pcr and race. the cdna sequence of 3gt consisted of 1548 bp open reading frame (orf) encoding 516 amino acid, the deduced ... | 2012 | 23016307 |
| cinnamate metabolism in ripening fruit. characterization of a udp-glucose:cinnamate glucosyltransferase from strawberry. | strawberry (fragaria x ananassa) fruit accumulate (hydroxy)cinnamoyl glucose (glc) esters, which may serve as the biogenetic precursors of diverse secondary metabolites, such as the flavor constituents methyl cinnamate and ethyl cinnamate. here, we report on the isolation of a cdna encoding a udp-glc:cinnamate glucosyltransferase (fragaria x ananassa glucosyltransferase 2 [fagt2]) from ripe strawberry cv elsanta that catalyzes the formation of 1-o-acyl-glc esters of cinnamic acid, benzoic acid, ... | 2006 | 16443693 |
| stilbene synthase gene transfer caused alterations in the phenylpropanoid metabolism of transgenic strawberry (fragaria x ananassa). | the gene encoding stilbene synthase is frequently used to modify plant secondary metabolism with the aim of producing the self-defence phytoalexin resveratrol. in this study, strawberry (fragaria x ananassa) was transformed with the ns-vitis3 gene encoding stilbene synthase from frost grape (vitis riparia) under the control of the cauliflower mosaic virus 35s and the floral filament-specific fil1 promoters. changes in leaf metabolites were investigated with uplc-qtof-ms (ultra performance liquid ... | 2009 | 19443619 |
